I have $2$ files, one is A$.$bin $(5000$ square matrix$)$ and the other is B$.$bin $(5000$ square matrix$)...$I multiply these two matrices and save the result as D$.$bin file as a $5000$x$5000$ matrix $($For example, cell $(0,0)$ of matrix A is $5$ and cell $(0,0)$ of matrix B is $2.$

and will multiply it and place it as $10$ in cell $(0,0)$ of matrix D$)$ I want you to write C code and use MSMPI
